Abstract (en)
A linear array detector (LA) for use in creating an x-ray image after passage of a thin collimated curtain of these x-rays through an object is described. This detector has alternating portions of first and second types (Tk5,Tn5) along its length and of pixel size as measured along the length of the linear array detector. Each of the said types comprises scintillator material, optionally filter material (F), and detector means for detecting light signals corresponding to x-ray impingement on the scintillator material. The said first type of portion having a thickness of scintillator material and/or a filter such that the scintillator material provides a signal corresponding to the passage of the x-rays through an object or portion of that object of relatively low molecular weight and the said second type of portion having a thickness of scintillator material and/or a filter such that the scintillator material provides a signal corresponding to the passage of the x-rays through an object or portion of that object of relatively high molecular weight. In this way one can discriminate between higher and lower molecular weight materials and for example show potential explosive material which tends to be lower molecular weight material.
